fixed cells

110 and 120, carry, locate, arrange or otherwise transmit PCB90.

The PCB support apparatus can also comprise downside bearing unit 140 (referring to Fig. 6), and this unit has the structure of supporting PCB90 bottom surface.Downside bearing unit 140 moves through the direction that makes progress in the PCB90 lower edge and supports the bottom surface of PCB90; Therefore; Can the height of PCB90 be adjusted to roughly corresponding with the height of first and second

movable plate

112 and 122 so that PCB90 for example roughly is in same plane with plate 112,122.That is, when between first and second

fixed cells

110 and 120, carrying PCB90, downside bearing unit 140 raises with supporting PCB90 and regulates the height of PCB90.

Downside bearing unit 140 comprises vertical movable plate 141, and this movable plate can be from pedestal 100 upwards to move with downward direction.Downside bearing unit 140 also comprises from vertical movable plate 141 upwardly extending supporting wing plate 142 and fulcrum posts 143.The both sides of the bottom surface of supporting wing plate 142 supporting PCB90, and, the middle body of the bottom surface of fulcrum post 143 supporting PCB90.

The PCB support apparatus can also comprise vacuum nozzle 150, and this nozzle applies vacuum fixing PCB90 vertically through the bottom surface to PCB90.Vacuum nozzle 150 can move with downside bearing unit 140, edge direction up or down; So that after supporting wing plate 142 and fulcrum post 143 contacts the bottom surface of PCB90, vacuum nozzle 150 applies vacuum pressure through the bottom surface to PCB90 and fixes PCB90.

Below, will the operation of equipment that is used to support PCB with said structure be described.

PCB90 is installed on the PCB conveying equipment 130 of PCB support apparatus, and, between first and second

fixed cells

110 and 120, it is carried.Before installing PCB90 additional; For example; In one embodiment; Through making second guide unit 121, thereby can first and second guide units 111, spacing between 121 be adjusted to roughly the width (that is the spacing between the edge 91 and 92) corresponding to PCB90 toward or away from the motion of first guide unit 111.

The front and back end of the bottom surface of PCB90 is by first and

second conveyer belts

second conveyer belts

131 and 132 of PCB conveying equipment 130 rotate, between first and second

fixed cells

110 and 120, carry PCB90.

First and

second conveyer belts

131 and 132 of PCB conveying equipment 130 are lower than first and second fixed

heads

112 and 122 and constitute; So that PCB90 is when being carried by first and

second conveyer belts

131 and 132; Not can with other parts, interfere like first and second fixed heads 112 and 122.Downside bearing unit 140 is regulated the height of the PCB90 that is carried so that roughly be in same plane with the plate 112,122 of first and second fixed cells 110 and 120.When side bearing unit 140 moves under PCB90 in the upward direction instantly, through supporting PCB90 from vertical movable plate 141 upwardly extending supporting wing plates 142 and fulcrum post 143.First and second sides and first and second

movable plate

112 and 122 that downside bearing unit 140 rises until PCB90 roughly are in same plane.

Fig. 7 is the end view of the PCB support apparatus in the displayed map 3, and this equipment can be carried out printing operation along the past print direction backward; Fig. 8 is a plane graph, and it has schematically shown the mode of operation of PCB support apparatus shown in Figure 7.

When PCB90 and first and second

movable plate

112 and 122 roughly are in same plane,, PCB90 is bearing between them according to print direction.In printing operation, solder flux is applied on the surface of PCB90.When rolling through rubber solder flux is pressed in PCB90 when going up, the print direction of solder flux can be for from the place ahead of PCB90 backwards or from the rear of PCB90 forward.Roll through rubber, PCB90 is exerted pressure, thereby cause PCB90 to move along print direction along print direction.In order to prevent the motion of PCB90, confirm the direction of motion of PCB90 according to print direction, and, operate first and second

fixed cells

110 and 120 to avoid the motion of PCB90.

When print direction be from first edge 91 of PCB90 when second edge 92 of PCB90 (that is, in the past backward), because from the pressure of printing equipment, PCB90 is motion backward often.In this case, second movable plate 122 at second edge 92 of supporting PCB90 and 124 operations of second retainer are not so that PCB90 can move along print direction.

In this case, the work of second actuator 123 so that second movable plate 122 move along outward direction so that back surface contact second retainer 124 of second movable plate 122.When the back surface of second movable plate 122 contacted second retainer 124, because second retainer can limit the outside motion of second movable plate 122, therefore, second movable plate 122 this moments can not be with outside direction motion.

When second movable plate 122 and second actuator 123 have quit work, 113 work of first actuator so that first movable plate 112 move along inside direction, thereby PCB90 is pressed in or is clamped between the plate 112,122.Shown in Fig. 7 and 8, PCB90 is supported by the supporting wing plate 142 and the fulcrum post 143 of downside bearing unit 140, but fixing.Therefore, when first movable plate 112 was pushed first edge 91 of PCB90, PCB90 was towards 122 motions of second movable plate, and therefore, second edge 92 contacts second movable plate 122.

In this state, because second edge, 92 contact second movable plate 122 and the PCB90 of PCB90 can further not move along direction backward, therefore, the PCB support apparatus can support PCB90 reliably during printing operation.

Fig. 9 is the end view of the PCB support apparatus in the displayed map 3, this equipment can along from after forward print direction carry out printing operation; Figure 10 is a plane graph, and it has schematically shown the mode of operation of PCB support apparatus shown in Figure 9.

When print direction be from second edge 92 of PCB90 when first edge 91 (promptly from after forward), because by the printing equipment applied pressure, PCB90 is often with print direction motion (forward).In this case, first movable plate 112 at first edge 91 of supporting PCB90 and 114 work of first retainer are not so that PCB90 can travel forward.

In this case, shown in Fig. 7 and 8, PCB90 fixes with the mode relative with PCB.That is, the work of first actuator 113 so that first movable plate 112 move along outward direction so that back surface contact first retainer 114 of first movable plate 112.When the back surface of first movable plate 112 contacted first retainer 114, because the outside motion of first retainer, 114 restrictions, first movable plate 112, therefore, first movable plate 112 was fixing, thereby it can not further move along outside direction.

When first movable plate 112 fixing, when therefore first actuator 113 has quit work, 123 work of second actuator so that second movable plate 122 move along inside direction, thereby PCB90 is pressed in or is clamped on first movable plate 112.Shown in Fig. 9 and 10, PCB90 is supported by the supporting wing plate 142 and the fulcrum post 143 of downside bearing unit 140, but fixing.Therefore, when second movable plate 122 was pushed second edge 92, PCB90 was towards 112 motions of first movable plate, and therefore, first edge 91 contacts first movable plate 112.

In this state, because first edge 91 of PCB90 contacts first movable plate 112 and PCB90 can further not move along direction forward.Therefore, the PCB support apparatus can support PCB90 reliably during printing operation.

When according to print direction, when being bearing in PCB90 between first and second

fixed cells

110 and 120, vacuum nozzle 150 work are with supporting PCB90, so that provide vacuum pressure to keep it to be vertically oriented through the bottom surface to PCB90.

When setting up the supporting of PCB90, can be to printing operation adjustment PCB90.In one embodiment, can aim at PCB90 so that carry out printing operation through the aligning equipment 160 (referring to Fig. 3) that is installed in pedestal 100 belows.Aligning equipment 160 makes pedestal 100 move or pedestal 100 is rotated regulating the angle of pedestal 100 along x-axis direction and y-axis direction, thereby regulates the position of PCB90 so that carry out printing operation.

When accomplishing the adjustment of PCB90, carry out printing operation so that solder flux is applied on the surface of PCB90 with predetermined pattern.When accomplishing the printing operation of PCB90, from printing equipment, discharge through PCB conveying equipment 130 conveying PCB90 and with it.Immediately, carry another PCB and will repeat aforesaid operations through PCB conveying equipment 130.
